Forceps for intraocular foreign body

Abstract

The invention discloses a tweezers for intraocular foreign body, which comprises a hand-held component, a sleeve component, a protection component, a first driving component and a second driving component, and the sleeve component includes an outer sleeve and an inner sleeve which fit into each other; One end of the outer sleeve is connected with the hand-held assembly; the inner sleeve is driven to move relative to the outer sleeve through the first drive assembly; tweezers are connected to the outer end of the inner sleeve; The protective component is covered on the other end of the outer sleeve; the protective component is provided with a magnetic component. The invention facilitates the removal of intraocular foreign bodies, is applicable to different shapes of intraocular foreign bodies, and does not cause secondary damage to the eyes.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to tweezers for intraocular foreign bodies. Background technique [0002] Many patients with ocular trauma often see a foreign body flying into the eye quickly, causing acute vision loss and destruction of the intraocular structure. The purpose of the operation is to remove the foreign body in the eye as soon as possible, and minimize the damage to the surrounding intraocular tissues. The routine operation method is to make three puncture channels on the sclera 4mm behind the limbus of the eyeball, and use the corresponding intraocular instruments to extend into the eye from the puncture channels to remove the lesion, pull the adhesion tissue, and take out the foreign body, so as to protect the important retina as much as possible. visual function parts. [0003] The existing tweezers for intraocular foreign bodies can enter the eye through the puncture channel. The head...

Problems solved by technology

However, many intraocular foreign bodies are irregular in shape, and they are easy to fall off during the pulling process after being clamped. Most of the foreign bodies have sharp shapes, and if they fall off the eye, they will cause serious secondary damage to the retina. During surgery, they often fall off when they are pulled out after being clamped many times. Cases leading to serious iatrogenic injury

[0004] Due to the above defects, the intraocular foreign body tweezers need to be improved. It is urgent to invent a foreign body tweezers that can better grasp and wrap the foreign body in the eye. Once the foreign body is caught, it can be taken out smoothly without secondary problems. The case of falling off once, causing iatrogenic injury
